reconnection bug with ath9k

reconnection bug with ath9k

[John Ettedgui]

Hello,

I have a connection issue between my wireless card and my router.
Basically the first time it connects fine, then for some reason it
disconnects and then it is quite hard to reconnect.

With wicd, it would just not see any network anymore.
I switched to network manager and thought the issue was solved but
when I have this issue it keeps popping up asking me for the password
to use to connect (I am using wep2 personal).

rmmod ath9k
modprobe ath9
fixes the issue in most case.

Here is my setup:

I have a wifi card with an atheros chip:
05:04.0 Network controller: Atheros Communications Inc. AR5008
Wireless Network Adapter (rev 01)

I am using the module in the kernel that gets loaded automatically:
ath9k                  77563  0
ath9k_common            4902  1 ath9k

I see this in dmesg:

I am in the USA, not sure why it says the country code is CN.

Since I did not get that issue with my previous linksys / broadcom
card I am guessing the issue lies within ath9k but I could be wrong...

This is NM version: 0.8.1-1

Not sure what else to report...


Thank you!
